SHOE-SOLE.

Application led November 17. 1917.

2b a!! lr/mm it muy concern lie it known that i. .'tnnlsox T. S.\l'.\'n|-:|:s. a citizen of the lfnited States, and resident of Chicopee, Massaehusetts, have invented eeitain new and useful llnproveiuenta` in Shoe-Soles", of whit-h the following' is a specification. A

My' present invention concerns a hoot or shoe sole of the general type diselosed in application for Letters Patent. of the United States, filed by me Ahigust 7th, 1914'. Serial Number 184,951. and particularly to means by which such a eonlposite sole may be attached to the upper of the shoe.

The invention eonsits in the features and combination and arrangement of arts hereinafter vdescribed and particular lv pointed out in thlaims. i

'lipyl and thewelt The. channel or slit in-itho edge ofAV the sole maydielformed after Vthesole. is molded with it. .fibrous material in? eorporated therein, o1` this rl vide the attaching lip1` may be produced during7 the. molding of the sole, as Will be hereinafter described. Tn Fig. 4 I show an insert piece of fahl'ic of diShLform 'which the compound may pass to unite, the said Ieompound living on opposite sides Vof This insert piece may be combined with or incorporated with the rubber sole by a molding or attaching lip or 6o he entire solle, "buttulnnel to prohavingr perforationa throughV operation, as inother moldV pendicularly from the face of the sole at the desired distance from the edge and it may be anchored in different Ways.

Fig. 9 illustrates how the lip 1 may be made to extend up per endicularly from the face of the sole. In t is figure 1 is the insert piece; and 1 the li thereof. 3 indicates the body portions of t e sole as in the previous figures. 10 is the mold member, and 8', 8" are also mold members, these latter members havin between them the recess 12 for receivin t e perpendicular lip. 11 indicates the owel pin and 9X is a mold portion correpondin substantially to the member 9 of ig. 5 ut attached to one of the ortions. The recess 12 rprovides a free t for the lip portion 1. The

coating of ysoft compound upon the lip and upon the surface of the sole stock as laid up, flows under the heat and pressure of curing .into any space in the recess 12 not occupied by the fabric strip.

Fig. 10 showsithe mold modified at the meeting point of the members 8', 8, to cure the Strip at a different angle from that shown in Fig. 9. The formation of the lip in the positions indicated in Figs. 9 and 10 will enable the sole to be attached to an upper directly as in the case of a boot or shoe comprising rubber, by cementing the lip di rectly to the upper and recuring therewith to et a perfect union.

fter stitching the lip to the upper the channel 2 may be 'closed by cementing` its up er and lower Walls together.

n Fig. 'i' I show a complete sole in edge AView embodying my invention, this sole 'being like that described in the above mentioned application, having a stil-f shank portion a and a fiexible tread portion b. At c is indicated in dotted lines the layers of rein forcing fabric extending throughout the shank and terminating` at different points i-n echelon Within the tread portion and the attachinglip is indicated at 1 extending along the upper edge of the sole' throughout both the len h of the stiff shank portion and the fleXi le treadpart, said lip in all parts being of such flexible character that it is adapted for attachment to the leather upper.

This sole may embody all the features described in said application in addition to the attaching li What I c aim is:

1. A rubber sole having a channel in itsl edge near its upper surface with an attaching lip forming the upper wall thereof, said lip comprising fabric extending inwardly beyond the bottom of the channel and united with thc rubber compound of the lmain body of the sole, substantially as described.

2. A rubber sole having a channel in its edge near its upper surface with an attaching lip forming the upper wall thereof, said lip comprising fabric coated with rubber extending inwardly beyond the bottom of the channel and united with the nrain body of the rubber compound of the sole.

3. A rubber solo having a sheet of fabric vulcanized therewith, said fabric having un unattachcd flexible extension overlyingr a portion of the sole leaving a channel between itselfl and the underlying portion of said sole and thereby providingl an attach-- ing lip, substantially as described.

4. A sole for a boot or shoe having a tread and a relatively stifiI shank both coluprisinggl vulcanized rubber and an attachingr lip extending` along the upper ortion of the sole and fiexible both along t 1e stiff shank and along the tread, substantially as described.

5. A sole for a boot or shoe having a tread and a. relatively stiff shank both comrising vulcanized rubber and an attaching iip extendingr along the upper rtion of the sole and flexible both alongi tie stiff shank and along the tread,.said llp comprising an extension of fabric vulcanized with the shank and tread portions of the solo, substantially as described.

In testimony whereof, I aiiix my signature.
